I don't know what the final drive ratio is for a 1200 but an 1100 is 3.10. If the trike tires are close to the same diameter as the bike tires then the gearing will be off quite a bit. A search around some four wheel drive sites might reveal a calculator. I think the formula will look something like this:
old tire diameter/old final drive ratio = new tire diameter/new final drive ratio
